3 Claims.

My invention relates to gas burners.

The object of my invention is to provide a gas burner of a type topromote effective combustion of a mixture of inflammable gas and air. Afurther object of my invention is to provide a gas burner of the kinddescribed which embodies the use of concentric bowls or annulardeflectors and a core centrally positioned over a burner of a kind nowin common use, and a perforated dome.

A still further object of my invention is to provide a burner of thekind described in which passages are arranged to cause an impingement ofthe flow of an inflammable mixture in order to approach a more completecombustion.

These and other objects will hereinafter be more fully explained:

Referring to the drawing in which like characters apply to like parts inthe different, views:

Fig. 1 is a plan view of the burner, the perforated dome not shown.

Fig. 2 is an elevation of the burner with parts broken away andpartsshown in section for the purpose of illustration.

Fig. 3 is a perspective view of one of the annular deflectors.

A burner of a conventional type now in common use, comprising a hollowcylindrical body 1, having perforations or jets 2 on its upper surface,a mixing chamber 3, and a valve 4 is connected to a supply ofinflammable gas at A.

The core 5 and the annular deflectors 6, 7, and 8 respectively areconcentrically positioned on the burner as shown. The core 5 is shapedto flare at the points B and C.on its periphery. The deflector 6 isformed to flare at D and E on its outer, and at Fon its inner,periphery. The deflector 7 is formed to flare at G on its outer, and atH on its inner, periphery. The deflector 8, which in the instanceillustrated is the outer deflector, is formed to flare at I on its innerperiphery. A dome 9, perforated at J is positioned as a top for theburner and rests on the deflector 8 at K. Vents L are provided at thelower extremity. of each of the rings.

The flared portions onthe various deflectors and on the core 5 arepositioned to provide a tortuous path between the walls of thedeflectors and between the inner deflector and core, for the buminggaseous mixture in the manner indicated by the arrows; Impingement ofthe mixture against the surfaces of the deflectors occurs at each flaredportion during its upward movement between the deflectors and betweenthe inner deflector and core, and finally against the dome beforeescaping through the perforations J. v

The primary addition of air is accomplished at M and the secondaryaddition of air occurs through the vents L.

The deflectors and core may be composed of any material capable ofwithstanding high temperatures; however a refractory material ispreferable.

In operation the burner described functions to provide a very effectivecombustion of inflammable gaseous mixtures, under comparatively lowinitial pressures. Such modifications may be employed as lie within thescope of the appended claims and what I claim as new and desire tosecure by Letters Patent is:

1. In a burner of the kind described, in combination with a perforatedcylindrical discharge device, a plurality of annular deflectors, flaredportions on the walls of the deflectors, a core, flared portions on thecore, the said core and deflectors concentrically disposed on thedischarge device and arranged to receive a gaseous mixture therefrom.

2. In a burner of the kind described, a discharge device for a gaseousmixture, a plurality of bowl shaped annular deflectors, 'said deflectorsconcentrically disposed, flared portions on the surfaces of thedeflectors, a core, said core positioned concentric to the deflectors,flared portions on the core, a dome having perforations, the saiddeflectors positioned on the'discharge device to re- .ceive the gaseousmixture and the said dome positioned above the deflectors.

3., In a burner of the kind described, a discharge device for a gaseousmixture, a plurality of bowl shaped annular deflectors, flared portionson the surfaces of thedeflectors, a core, flared portions on the core,the said core and deflectors concentrically positioned on the dischargedevice and arranged to receive a gaseous mixture therefrom.
